Add a static IP range to an existing network?

Hi.

Our small network here is running out of IP's --

Every device is assigned a static IP in the 10.9.8.xxx range. DHCP is off. I am thinking we can just start a new range 10.9.7.xxx for new PC's, but how? Will those PC's just work fine, finding our servers in the 10.9.8.xxx range? One thing to note here is we do have a firewall appliance acting as the gateway at 10.9.8.1, so perhaps something there has to be added.

I'm a software developer, and not a network guy -- we lost our guy a year ago, and I've been keeping things running ever since ... so bear with me.

Any suggestions?

Thanks!

We used 255.255.255.0 on all the PC's. Would we have to go around and change them all to 255.255.255.0.0 ? Then, we could add the 10.9.7.xxx PC's ?

Yes, you need to change the subnet mask everywhere, and (as said) then you are free to use 10.9.x.x.

Ok, I will try a few PC's (and a server) as an experiment.

Here's a more basic question: Why do we generally use 255.255.255.0? Why don't people just use 255.255.0.0 or 255.0.0.0? Is it a security issue, or does it limit some sort of network traffic?

Thanks
